NCT00781586
First received: October 28, 2008
Last updated: November 20, 2013
Last verified: November 2013
  Purpose

The study is considered research because efficacy (how well a drug works) information is needed in healthy, 25-45 year-old, female subjects with moderate caffeine intake. The investigational product is available in the United States without a prescription (over-the-counter) as a nutritional supplement. The purpose of this study is to assess whether One-A-Day Weightsmart Advanced is safe and can increase metabolism and perceived energy in female subjects compared with caffeine or placebo (inactive drug). Participation in this study will last approximately 4 weeks and require about 4 outpatient visits to St. Luk's-Roosevelt Hospital Center. About 21 subjects are expected to participate in this study.

Primary Outcome Measures:
  • Area Under the Curve (AUC) of RMR for the first 2 hours [ Time Frame: Primary efficacy endpoints are area under the curve (AUC) over the first 2 hours and the last 2 hours of Resting Metabolic Rate and Respiratory Quotient ] [ Designated as safety issue: No ]
  • AUC of RMR for the last 2 hours [ Time Frame: Primary efficacy endpoints are area under the curve (AUC) over the first 2 hours and the last 2 hours of Resting Metabolic Rate and Respiratory Quotient ] [ Designated as safety issue: No ]
  • AUC of Respiratory Quotient (RQ) for the first 2 hours [ Time Frame: Primary efficacy endpoints are area under the curve (AUC) over the first 2 hours and the last 2 hours of Resting Metabolic Rate and Respiratory Quotient ] [ Designated as safety issue: No ]
  • AUC of RQ for the last 2 hours [ Time Frame: Primary efficacy endpoints are area under the curve (AUC) over the first 2 hours and the last 2 hours of Resting Metabolic Rate and Respiratory Quotient ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Perceived Energy scales - Visual Analog Scale (VAS) [ Time Frame: Change from baseline for Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP) respiration, average heart rate over 1st 20 minutes, average heart rate over last 20 minutes, and temperature ] [ Designated as safety issue: No ]
  • AUC for heart rate for the first 2 hours [ Time Frame: Change from baseline for Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP) respiration, average heart rate over 1st 20 minutes, average heart rate over last 20 minutes, and temperature ] [ Designated as safety issue: No ]
  • AUC for heart rate for the last 2 hours [ Time Frame: Change from baseline for Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP) respiration, average heart rate over 1st 20 minutes, average heart rate over last 20 minutes, and temperature ] [ Designated as safety issue: No ]
  • Change from baseline for Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP), respiration and temperature [ Time Frame: Change from baseline for Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP) respiration, average heart rate over 1st 20 minutes, average heart rate over last 20 minutes, and temperature ] [ Designated as safety issue: No ]
